What are the benefits of combining advanced lighting control strategies in the same space? Are the energy-saving benefits of lighting controls persistent over time? Can advanced lighting controls be successfully applied to open offices given concerns about jurisdiction conflicts, lighting uniformity, etc.? Can they enhance worker satisfaction? A new office lighting field study addresses these questions. Involving about 90 workers in a real-world open-office environment, the one-year study determined that occupancy sensing, daylight harvesting and individual occupant dimming control worked together in the building to produce average energy savings of 47% while correlating with higher occupant environmental and job satisfaction. The study demonstrates that sophisticated lighting control strategies can be combined successfully to generate persistent, large energy savings in open-plan offices while improving occupant satisfaction with their jobs and workspace.
As part of its mission to promote energy efficiency and innovation for the benefit of its customers, the New York Power Authority (NYPA) gives special emphasis to demonstrating new energy-saving technologies. Along these lines, NYPA installed AddressPro® Digital Dimming—an advanced lighting-control technology—from Universal Lighting in several areas of its main administrative office building in White Plains. This was done as part of the wide-ranging measures NYPA has undertaken in recent years to augment the seventeen-story building’s energy efficiency for lowering electric bills and reducing carbon emissions.
Vermont-based manufacturer NRG Systems in 2005 built a new headquarters carefully crafted to reflect the company’s commitment to the environment, the community and its employees. The 46,550 square foot facility, which includes office, manufacturing and warehouse space for company-produced wind monitoring equipment, was designed to minimize environmental impacts and maximize energy conservation.
The first design goal was to find ways to minimize energy needs in all areas of building operation, including heating, cooling and lighting. The second goal was to provide as much energy from renewable sources as possible. Company owners were willing to make an upfront investment to ensure significant long-term savings.
Naomi Miller of Naomi Miller Lighting Design specified the electric lighting and Andy Shapiro of Energy Balance, Inc. developed the facility’s daylighting plan. The two designers collaborated with Watt Stopper/Legrand to select energy saving controls that would meet the ambitious criteria of the project.
A number of studies demonstrate that personal dimming can result in higher productivity—specifically in the metrics of vigilance, motivation and satisfaction—and also in energy savings. This dual impact can result in an improved bottom line and more satisfied employees and tenants. These advantages are resulting in a significant new trend towards adoption of personal dimming solutions among designers and building owners.
This white paper makes the case for personal control, in particular giving occupants the ability to control their own light levels through dimming.
Pier 69 on Seattle’s historic waterfront was built in 1931 to warehouse rolls of metal for the production of canned salmon containers. The only concrete pier on the waterfront, Pier 69 stretches over 750 feet long and 135 feet wide. Hewitt Isley tackled this stolid building to create a new home for the Port of Seattle’s administrative headquarters. Their dynamic reno-vation created what the Seattle Weekly named “one of the grandest indoor spaces in the Northwest.”
